Title

COMPOSING THE PNEUMATIC SEED METERING DEVICE IN PUNCH PLANTER AND LABORATORY EVALUATION OF IT

Pages

  11-23

Abstract

 In the present research a dibble PUNCH PLANTER with PNEUMATIC seed metering device was constructed. These planters punch holes at equal distances and depths in soil and then place a single seed in each hole and cover it. The laboratory evaluation was conducted on grease belt. In this way, the effect of forward speed (2.8, 3.7, 4.6, 5.5, 6.4 and 7.3 km/h) on; multiple indexes, quality of feed index, miss index, PRECISION and percent of holes with seed in them was considered. All of these indices based on theoretical distance between plants within a row and indicate the accuracy in seed placement for planters using single seed metering mechanisms. According to the results of these experiments the increase of forward speed resulted in increase of PRECISION and decreasing the percent of holes with seed in them, without any remarkable effect on the multiple indexes, miss index and quality of feed index. Furthermore 6.4 km/h speed was recommended as the best forward speed.
